If EF% is a most flawed LV functional parameter,.. why we Insist HF to be classified based on it ?
Heart failure has been classified in many ways, with prevailing levels of our knowledge and ignorance. It is based on a variety of factors like rapidity of onset, etiology, chambers involved, hemodynamics, etc.  Forward vs backward failure Acute vs chronic failure RV/LV or Biventicular failure  Systolic vs diastolic heart failure High output vs low out failure Ischemic vs non-ischemic failure  Reversible vs Refractory HF  None of them have really helped at the bedside though it helped us understand the condition. Now, in the last decade, we have crash-landed on our favorite obsession to classify HF ie based...

Cardiac arrest with anterior-inferior STEMI: Guess the value of the initial ED high sensitivity Abbott troponin I
A ~40 year old woman started having chest discomfort.  She called 911 after an uncertain amount of time.  EMS arrived and recorded thisprehospital ECG:Obvious Anterior and Inferior STEMI, consistent with LAD occlusionAfter recording this ECG, the patient went intoventricular fibrillation.She was rapidly defibrillated.The cath lab was activated by the paramedics.She arrived complaining of chest pain, with a BP of 110/70.An ED ECG was recorded:It looks worse stillAside: Should the patient receive antidysrhythmics to prevent recurrent VT/VF?  See discussion below on both beta blockers and other anti-dysrhythmic...

Is it safe to reduce blood pressure medications for older adults?
“Doctor, can you take away any of my medications? I am taking too many pills.” As physicians, we hear this request frequently. The population most affected by the issue of being prescribed multiple medications, known as polypharmacy, is the elderly. Trying to organize long lists of medications, and remembering to take them exactly as prescribed, can become a full-time job. In addition to the physical and emotional burden of organizing medications, older adults are at increased risk for certain types of side effects and potential worse outcomes due to polypharmacy. A common source of prescriptions is high blood pressure...

Hypoxia and LV dysfunction: Let us learn more from “ COPD, COVID-19 and Tetralogy of Fallot ”
Superficially, tissue hypoxia might look similar to Ischemia but differs in one important aspect. Though the hypoxic myocardium is short of oxygen, the respiratory excreta from cells ie Co2, lactic acid, and free radicles are promptly cleared and flushed as blood flow is normal. Hence, generally acute  Ischemia of tissues is more cell threatening than regional hypoxia at any organ level. How do you classify hypoxia? we need to go to physiology classes again.There are 4 types. Ischemic -Hypoxia, systemic hypoxia, Anemic hypoxia, Histo-toxic hypoxia.A good reference to read (Ošt’ádal B., Kolář F. (1999) Myocardial Hy...

What ’ s the relationship between JVP and PCWP/LVEDP?
This study elegantly shows a correlation (or lack of it) in different subsets of heart failure. It tells us very clearly If JVP(RAP) is not correlating or disproportionate to PCWP, it implies RV dysfunction. 2. This paper suggests a really useful scheme to classify heart failure as concordant and discordant with reference to right and left heart. It throws some interesting facts. I guess it will help us guide diuretic management and prognosticate chronic heart failure.

Lifestyle changes are important for managing atrial fibrillation
Atrial fibrillation (afib) is a common heart rhythm disorder in which the upper chambers of the heart (the atria) beat fast and irregularly. Afib commonly causes recurrent symptoms, usually palpitations and shortness of breath, and can negatively affect quality of life. Afib also substantially increases the risk of stroke, and is also associated with heart failure, high blood pressure, and diabetes. People with afib routinely require lifelong treatment with blood thinners, to prevent blood clots that can lead to strokes. Doctors are only recently understanding the importance of lifestyle factors in treating afib. Modifiabl...

Gender differences in cardiovascular disease: Women are less likely to be prescribed certain heart medications
Cardiovascular disease (CVD) is the leading killer of both women and men in the US. Despite the significant impact CVD has on women, awareness and education for women’s heart disease has historically been low. A recent study, based on data from over two million patients, suggests that women were less likely to be prescribed aspirin, statins, and certain blood pressure medications compared to men. CVD is a group of diseases involving the heart or blood vessels. It includes high blood pressure (hypertension), coronary artery disease, heart attacks, heart failure, heart valve problems, and abnormal heart rhythms. CVD ca...

Hypokalemia with heart failure – Cardiology MCQ – Answer
Hypokalemia with heart failure – Cardiology MCQ – Answer Which of the following is the last option in a patient with hypokalemia and heart failure? – Correct answer:  1. Oral potassium supplementation Adding ACE inhibitors or ARB and MRA are much more important for the long term prognosis of heart failure. If these have not been added, adding them alone may control hypokalemia. These drugs should be uptitrated before considering oral potassium supplements. Thiazides have a higher potential to cause hypokalemia (≈0.6 mmol/l) than loop diuretics (≈0.3 mmol/l) in the usual doses. Back to question Refere...

Serum vs plasma potassium – Cardiology MCQ – Answer
Serum vs plasma potassium – Cardiology MCQ – Answer Comparing serum and plasma potassium values – Correct answer: 1. Serum values are higher by 0.1 to 0.4 mmol/l Potassium is continuously released from cells during clotting. So serum values are higher than plasma values. So long waiting periods for analysis can cause spurious or pseudohyperkalemia. Same can occur if hemolysis occurs due to errors in collection.
